Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Depend on figure 1 As shown, the distributed solar cascade utilization system of the present invention includes a main power generation system I and a waste heat utilization system II.

[0025] The first heat exchanger 5 connects the main power generation system I and the waste heat utilization system II.

[0026] In the main power generation system 1, one or more high-temperature heat collectors 1, a steam turbine 2, a generator 3, an electrical storage device 4, and a circulation pump 6 are included. The high-temperature collector 1 gathers solar energy, converts it into thermal energy to heat water, and generates steam at a certain temperature and pressure to drive the steam turbine 2, thereby driving the generator 3 to generate electricity, and then the water vapor is circulated after releasing heat in the first heat exchanger 5 Th...

Abstract

The invention provides a distributed solar energy cascade utilization system and belongs to the field of solar energy utilization. The system mainly comprises a main solar energy generating system and a residual heat utilization system. In the main solar energy generating system, a high-temperature heat collector, a steam turbine, a first heat exchanger and a circulating pump are connected in turn to form a water circulating passage; an electric generator is connected with the steam turbine; and an electrical storage device is connected with the electric generator. In the residual heat utilization system, a first heat exchanger, a hot water system, a refrigerating system or a heating system and a circulating pump are connected in turn to form a water circulating passage, wherein the main generating system is connected with the residual heat utilization system through the first heat exchanger. The system aims to realize synchronous supply of cold, heat and electricity by using solar energy so as to meet the requirements of residents on basic energy sources in daily life.

Description

technical field [0001] The invention belongs to the field of solar energy utilization, and relates to an energy utilization system capable of producing various forms of energy. Background technique [0002] my country's total energy resources are relatively rich, but with a large population, there are many mountainous areas, deserts and grasslands, and the per capita energy resources are at a relatively low level in the world. The energy structure is unreasonable, mainly based on coal. The energy utilization rate is low, and it is one of the countries with the highest energy consumption per unit in the world. Under such a premise, renewable energy has gained worldwide attention, among which solar energy, which is the most abundant resource, has been the first to develop relatively rapidly. For mountains, deserts and grasslands, if the distributed energy cascade utilization system can be applied, a large amount of power investment and maintenance costs can be saved, and the...
